Parameters:
t - current value of the independent time variable
y - array containing the current value of the state vector
yDot - placeholder array where to put the time derivative of the state vector
Throws:
MaxCountExceededException - if the number of functions evaluations is exceeded
DimensionMismatchException - if arrays dimensions do not match equations settings
